RNAS C Practice Test Review 437 Questions with Verified Answers A capacitor and resisitor in parallel - CORRECT ANSWER will have same voltage across since in parallel. if in series, voltage drops would occur they can be treated together If the absolute pressure of a gas is increased from 3 atm to 4 atm at constant volume, then the absolute temperature of the gas will increase by: A. 25%. B. 33%. C. 67%. D. 75% - CORRECT ANSWER B. Assuming the validity of the Ideal-Gas law, PV = n...

there is a decrease in products - if K <<<< 1 of a weak acid, then (concerning products) decrease in pH - an increase in K and products will result in (concerning pH) Ka - equilibrium constant for ionization of acid increases - if the percent ionization increases, what happens to acid strength? K decreases - what happens to K as you deprotonate acids? weaker - do acid become weaker or stronger as you deprotonate them? no - do SA/SB have conjugates?

What is the proteome of the cell? correct answer: the full complex of proteins that can be produced using genetic material and post translational modifications What are some example of post translational modifications? correct answer: phosphorylation (signalling) GPI anchor (PM proteins) O-glycans (nuclear and cytosolic proteins) polyubiquitination (can induce protein degredation) How can you watch the purification of recombinant poly-His tagged GFP? correct answer: use Ni2+ immobili...

Unsaturated fatty acids - have one or more C=C bonds Saturated fatty acids - Have no C=C bonds What are the ways that biodiesel is produced commercially? Which method is the predominant method? - 1) Base-catalyzed transesterification of the oil with methanol and one used in lab. 2)Acid-catalyzed esterification of the oil with methanol 3) Saponification of the oil to yield free fatty acids, followed by acid catalyzed esterification. Match the products and catalyst for the following tran...

Organic Chemistry Lab I (CHEM 237) Experiment 10: Phase Transfer Catalysis 100% Solved Objective: To examine the use of a phase transfer catalyst to effect an SN2 reaction in dichloromethane solution. The reaction will be conducted without extraction for product isolation. List the procedural steps, from start to finish, that are required to convert 2-naphthol and allyl bromide into allyl 2-naphthyl ether. - The reaction is performed on a small scale by mixing the alcohol, the haloalkane, ...

Organic Chemistry Lab I (CHEM 237) Experiment 10: Phase Transfer Catalysis 100% Correct List the procedural steps, from start to finish, that are required to convert 2-naphthol and allyl bromide into allyl 2-naphthyl ether. The reaction is performed on a small scale by mixing the alcohol, the haloalkane, and the phase transfer catalyst in a conical vial. Sodium hydoxide (base) is added to initiate the reaction. The reaction flask is covered and stirred to conduct reaction to prevent evaporation...

Acidity of α-Hydrogen: Carbonyl α-carbon: Next to the carbonyl carbon. α-Hydrogen: H of alpha carbons Oxygen pulls electron density out of these C-H bonds so it's easier to deprotonate the α-carbon of aldehydes/ketones. How do you increase the acidity of α-Hydrogen? - Resonance stability provided by the conjugate base - Resonance can stabilize enolate intermediate, since negative charge is distributd to more EN oxygen atom - Alpha hydrogen can easily deprotonate in basic solutions...
